Lightning arrester is an important electrical equipment in power network to protect power equipment from over-voltage. Normally, the action of the arrester and leakage current are monitored through the arrester monitor. Due to poor sealing, the monitor may enter water or moisture during operation, causing internal element corrosion, or other reasons, the monitor counter cannot operate normally, and the leakage current indication is not accurate. Therefore, according to 《The Regulations》, the arrester monitor should be checked once a year。
The reliability of counter operation is very important for power system. It is an important parameter to record the number of lightning strikes received by the arrester in normal operation. It can provide an important basis for the power system workers to inspect the arresters.
